He is best remembered for his roles in British films and television programmes of the 1950s, 1960s and 1970s, particularly his lead roles as a trendy fashion photographer in the hugely successful avant-garde mystery film Blowup (1966), directed by Michelangelo Antonioni and as a jazz pianist in Dario Argento's Deep Red (1975). Early in his career, Hemmings was a boy soprano appearing in operatic roles. In 1967, he co-founded the Hemdale Film Corporation. From the late 1970s on, he worked mainly as a character actor and occasionally as director.
